操作定义

“花生果酱三明治”的操作性定义是“使用抹刀先将花生酱涂抹到一片面包上，再将果酱涂抹在花生酱上，最后盖上另一片厚度相同的面包后所得到的成果。”

质量的操作定义

${\displaystyle F=m_{A}a_{A}=m_{B}a_{B}}$

${\displaystyle m_{B}={\frac {a_{A}}{a_{B}}}m_{A}}$

力的操作定义

${\displaystyle F_{s}=-kx}$

${\displaystyle F_{G}=-G{\frac {m_{A}m_{B}}{r^{2}}}}$

${\displaystyle F_{g}=mg}$

注释

1. ^ 概念型定义使用更基础的概念来对于术语给予定义。例如，术语“速度”可以用“移动距离”与“时间间隔”来给出定义。
